APPARATUS l-'OR REMOVING BURRS AND THISTLES FROM WOOL AND SIMILAR FIBERS.

SPECIFICATION forming part of Letters Patent No. 412,531, dated October 8, 1889.

Application filed May 25, 1889. Serial No. 312,167. (No model.) Patented in France October 19, 1888, No. 193,628 g in Belgium November 5, 1888, No. 83,847, and in England November 17, 1888,1To. 16,713.

To all whom it may concern:

Be it known that I, EDMOND NOUVELET, a citizen of the Republic of France, residing at Wignehies, in the Department of Nord and Republic of France, have invented certain new land useful Improvements in Apparatus for Removing Burrs and Thistles from Wool `and Similar Fibers; and I do'declare the fol=i lowing to be a full, clear, and exact 'description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

This invention has been patented in the following countries, to wit: France, October 19, 1888, No. 193,628; Belgium, November 5, 1888, No. 83,847 England, November 17 1888, No. 16,713.

In certain types of apparatus for removing burrs and .thistles from wool and similaifibers the crushing of t-he burrs and thistles is effected during the passage of the wool in the form of a ieece or iilm in a horizontal direction between a series of pairs of rollers placed side by side.` According to my improvements a dierent arrangement of rollers is employed, and they are placed upon each side of a vertical plane through which the wool falls under the combined action of the rollers and gravity.

I will proceed to particularly describe this invention with reference to the accompanying drawing, which represents in vertical section the essential'details of the apparatus, the framing, driving-gear, and other accessories being omitted for the sake of clearness, and also because the construction and arrangement of thesel accessories are well known.

In an apparatus constructed according to these improvements the wool is delivered to and spread upon an endless traveling apron A, which delivers it above and between the two upper rollers B B of the series of vertical rollers. These rollers are clothed with wire cards or with needle-points. The draw ing-rollers I I immediately below the card rollers and the crushing=rollers G C are each clothed with india-rubber or other similar elastic or yielding material. The number, diameter, and speed of all these rollers may be varied to suit the character and condition of the wool to be cleaned. The doffing-rollers D D are placed wider apart than the upper rollers and immediately below the crushingrollers. The cleansed wool is doifed from' the rollers C C by the doffers D D and falls upon a horizontal endless traveling table E, which delivers it to any desired position-as, for example, onto the truck F. At the back of each of the crushing-rollers there is fixed a knife or scraper H H with its edge bearing upon the surface of the roller, so as to clear therefrom the dbris which clings to it after passing the doffer. Below each knife there is a trough or receptacle G G', into which the dbris removed by the knife is received, and from whence it may from time to time be removed.

When tlie apparatus is in operation, the wool is formed into a iieece or film by means of the rollers B B. This fleece is then drawn and guided by the intermediate rollers I I and delivered to the crushingrollers C C. The crushed thistles, burrs, and other dbris, with aportion of the wool, adhere to the surface of the rollers, and are carried forward by their revolution until such of the wool as clings to them is removed by the doffers and added to the bulk on the apron E. The crushed burrs and other dbris are not removed by the doifers, but are carried forward until they are removed by the knives H H into the receptacles Gr G.

The hereinbeforedescribed combination In an apparatus for removing burrs and thistles from Wool and similar bers, the combination and arrangement of the vertically-disposed earding, drawing, crushing,

and doing rollers With the knives H H', the receptacles G G', and the endless traveling apron E, all substantially as hereinbefore described and shown.

In Witness whereof I hereunto set my hand in presence of two Witnesses.
